He was not suited for the job. The bureaucracy controlled him rather than the other way around. He basically let it run amok by having no talent or skill to run a department of that size and scope. I don’t believe he was part of an establishment conspiracy against Trump and he did it on purpose...but he was completely aloof in what he was actually dealing with and had no ability whatsoever to manage it. His appointment was a massive mistake - for the reasons just mentioned, and also the loss of the Senate seat that also resulted.
I dont blame Sessions he is way to mild mannered to have run the corrupt DOJ, I dont think Trump OR Sessions had any idea what the hell they were walking into!! Obama made it his mission before leaving office to weaponize every damn department in the government making it damn near impossible for his successor to run the country! Obama and intel knew EXACTLY what they were doing Sessions was not the right person for the job I dont blame Sessions!!!
Hope and pray the same thing doesn’t repeat itself with Mark Meadows giving up his seat to be COS
